UNITED STATES JAMES K. LUM, OF SKOOKUMCI-IUCK, VASHINGTON TERRITORY.

IMPROVEMENT IN WINDMlLjLs..

Specification forming part of Letters Patent No. 24,472, dated June 21, 1859.

To all whom it may concern:

Be it known that I, JAMES K. LUM, of Skookumchuck, in the county ofThurstonA and Territory of Washington, have invented a new and Improved Arrangement of Means for Applying Wind as a Motive Power; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a side view of my invention, the

framing being in section; Fig. 2, adetached View of the ratchet device and fly by which the power of the wind-wheel is made to actuate or raise the weight.

Similar letters of reference indicate corresponding parts in the two figures.

The object of this invention is to obtain a more equitable or uniform motion than has hitherto been done by the use of a wind-wheel, and at the same time effect a saving in power; or, in other words, employ all the power of the wheel, so that the same may be laid up in reserve to be used when required.

The invention consists in having a weight connected with the wind-wheel in such a way that the same will be raised by the rotation .of the wheel and made to actuate or drive machinery by its descent when the wheel is stopped, the wind-wheel being employed to raise the Weight only instead of being directly connected with the machinery, as heretofore.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a framing, which may be coustructed in any proper manner to support the working parts. On the top of the framing A a cap I3 is placed and so fitted to the framing that it may rotate freely thereon. To the cap B a vane C is attached, and ashaft D is also placed in said cap in line with the vane C. The shaft D is allowed to rotate freelyin the cap B, and a crank d is on said shaft, said crank being within the cap.

On the outer end of the shaft D a hub Z) is attached, said hub having a series of radial arms c attached, on each of which a sail or wing d is placed loosely or so that it may turn freely thereon. These sails or wings are con- `nected by rods c with a sliding collarf on the shaft D, which collar is connected by a rod g with a bent-lever frame h, placed in the cap B and connected with a spring ax.

In the upper part of the framing A a vertical slide E is placed, said slide having two pendants j attached. The lower end of the pendant t' is connected to a lever F, which is secured in the framing A by a fulcrum-pin 7.".

To the crank ct of the shaft D a connecting-rod G is attached, the lower end of which is connected to the upper part ot' abentlever H, which has its fulcrnm at Z. The lower end of the lever H has two pawls ma attached to it, said pawls engaging with a ratchet o, which is secured vto the bottom of a y or fra-me I, which is fitted loosely on a vertical arbor J inthe lower part of the framing A. The pawl m is hooked at its end and actuates the ratchet with a pull or draw movement, while the pawl n actuates the ratchet with a thrust or shoving movelnent. The two pawls are kept in contact with the ratchet by a spring p. This will be clearly understood by referring to Fig. 2.

To the lower end of the arbor J a toothed wheel q is attached. This wheel gears into a pinion r, which is on the inner end of a horizontal shaft s, said shaft having atoothed wheel t on its outer end. The wheel tis provided with two sets of gears u o, one of which u engages with the pinion w of a governorshaft x, the other o gearing into the pinion g/ ot' a shaft e', having a balance-Wheel a on its outer end. The governor K may be of usual construction, and it has a lever L connected with its upper end, said lever having a weight b on its outer end. To the lever L a rod c is attached, the lower end of which is connected with a brake d', that acts against the periphery of the balance-wheel a. The power is taken from the shaft z or s. M is a shaft around which a cord or rope N is wound,and this cord or rope passes upward and is connected to one end of the lever F. (See Fig. l.)

The fly or frame I may be described as being formed of a circular disk e', with two uprights f f attached, connected at their npper ends by a cross-piece g. This y is allowed to rotate freely on the arbor J, and in each upright f a pulley h is placed, around which the ends of a cord t" pass, the two ends of said cord being wound on the arbor J in reverse directions, so that both ends will, as the fly rotates, be wound simultaneously on the Varbor J. The cord t" passes through a sheave j', which is attached to a cord or rope 7, that passes over a pulley O in the upper part of the framing, the cord \V passing through the end of lever F opposite to the end Where the cord N is attached, and having a Weight P attached to its end.

A is a shaft havin gaprojectionBattached to its end at right angles, which projection bears against the wheel a and prevents the rotation of the same and machinery connected with it when it is not required to operate. o

The operation is as follows: Suppose the machine to be at rest and asuicient wind blowing to drive it. The attendant, in order to put the machine in motion, turns the shaft- M by hand to slacken the cord N, and the spring` ctx will present the sails or Winged to the wind in consequence of actuating the sliding collar f. The wind-Wheel will then commence to rotate, and the cord i will, in consequence ofthe action of the rod G, lever A, pawls m n, and' ratchet o, and {1y-Wheel I, be wound on the arbor J. NVhen the wind-wheel cominencesto rotate, the machine may be driven,ii` desired,

the shaft A being turned so as to free theV projection B from the Wheel a. If the power actuates it so as to turn the sails d through the medium of the pendant 7l, lever h, and sliding collar f, so that the speed of the wheel will be checked. The wind-wheel, it will be seen, may be constantly changing its velocity vices are old and Well known; but,

Having described my invention, what I do claim as new, and desire to secure by Letters Patent, is- Y The employment or use of the y or frame I, placed on the arbor J and having the ends ot' t-he cord t' passing through it and attached to said arbor, said cords being also attached to the rope W ofthe weight P, the fly being operated by the Wind-wheel in such a manner as to admit of a simultaneous rotation of the arbor J.
